ANALYSIS OF CURVED SEGMENTALLY ERECTED PRESTRESSED CONCRETE BOX GIRDER BRIDGES

A method is presented for the analysis of curved segmentally erected prestressed concrete box girder bridges including time-dependent effects. The segments can be either precast or cast-in-place. The bridge cross section consists of a single box section with vertical or inclined webs and can have cantilever flanges. Time-dependent material changes such as creep and shrinkage of concrete as well as environmental effects such as humidity and temperature changes are accounted for. Prestressing in the longitudinal direction can be included in the analysis. A procedure is presented for specifying the structural configuration and erection sequence. Numerical results obtained are compared with experimental results and analytical results obtained by other researchers.
